IMPROVEMENT INEEA-riucrA'NDl vx-:NTuin-lflNoRuLRoAlxcARsl dSpecification lforming ,part of Letters Patent No. 74,386, datedFebruaryl1, 1868.

To all whom 'it may concern.'

`Be it known that I, SAMUELI LLOYD, of the city 'of- 'Washingtom haveinvented a new and useful VMethod of District of Columbia,

Heating and Ventilating Railroad-Cars; and thefollovving is a lfull,clear, and exact de- 'v scription thereof, reference be'ng -had -to theaccompanying drawing, and to the letters of reference marked thereon.

Figure 1 is a vertical section through alocof motive and heating-car.Fig. 2 is a sectional view of the coupling-pipe for conveying heatfromcartocar.. .The object of my invention is to heat and ventilatoatrainof railroad-cars by means of hot and cold air conveyed into thecars from.` apparatus on locomotive, and in a heating and ventilatingvcar, so as to obviate 'the' use of stoves in-each car, thereby givinggreatersef curity to life and economy of room and fuel.

l To enable others skilled in the art to makev and use my invention, Iwill describe it more fully, reference being had to the accompanyin gdrawing, and to the'letters marked` thereon.

Letter A, Fig. l., is a locomotive, having a lhood or opening, a,underneath the cowcatcher, for the purpose of gatheringthe air, which isconveyed by the pipe bV through the flue-chamber, kand s pirally aroundthe interior of the smoke-stack of the locomotive, thereby heating theair in the pipe. The pipe b, leaving the smoke-stack at its base, andypassing along the Voutside ofthe boiler, beneath the locomotive, isconnected with the horizontal pipe c, which connects by the iiexiblecoupling l) with another. horizontal pipe,.` d, whichis coupled with andconveys air to the passenger-cars, the hood a supplying a current ofpure air, which it is'unnecessaryto pass through water, and may beeither hot or cold, the change-being effected by means of the agitatorp, and exhausting into the receiver process.

Letters e e is a jacket inclosing, as far as practicable, the 'hot-'airchamberof the caloricengine. The cold air is received into the jacketby'means of a hood, r, and pipe y,'the supply being regulated by thevalve u. It` isn then passed around the hot-air chamber of thecaloric-engine by means of a spiralv line, the sections'ot' Vwhich aremarked f f ff, and by the pipe j j and valve m, forced by the blower Hthrough- 'the pipe o into the receiver Gr, or by means of the valve land pipe n, connecting with thevpipe o, passed directly into thereceiver by means of .the draft created by the movement of the train. A

Letter F.- is a'furnace Imany as necessary being used-jacketed and'regulated by valves, as described in the caloric-engine, and containinga spiral coil of pipe, g g, in the lire-chamber, through which a portionof v'the air passes, thereby giving a. greater heating-surface, theheated air from being conveyed by the pipe h the furnace The connectionwith the into. the pipe j at k.

-furnace may be closed or regulated by means of the valve Letter s is ahood for supplying the cars' with cool air, and is connected `with theblower H by means of the pipe p, and closed by the valve o when hot air1s used; but the air cali.

be takendirectly intothe receiver by `1neans of a connection between thepipesvt andl'o and the draft occasioned by the movement V,of the train.A

. Letter G is a receiver, partly iilled `with water, through which theair passes by means whose mouth opens under the of the -pipe o, water. y

Letter p is an the purified air from the receiver into the pas\ G bymeans ofthe pipe o, after 'first passing 4the exhaust hot air through adeodorizing for heating air-as agitator run bymeans of thecaloric-engine, or a pulley attached to the axleV i of the car, andvworking 'in the water directly over the mouth of the pipe o, therebydriving .the air through the. waiter, so that it will be y thoroughlyiiltered and freed of dust.

fw w which mayl be in front of the supply-pipe q as the car runs'.`

The tir, either het er een, is distributedthrough the cars by means of apipe or pipes, cased or not with a non-conductor of heat, running alongthe 'bottom of the cars, and

havin gone or more registers .openinglin each. car.

- The open end of the Vfixed conductingpipe of the last car can beclosed with a screwcap, so that all the air will pass into the cars',

'each -car being provided with one or more' Ventilating-hoods on top' ofeach car, Awith valve-openin gs, Vso as to regulate the tempera;` tureand ventilation. i

Letters'd d, Fig. 2, are portions of thevxed;

'conducting-pipes, and aremade of any suitafl bie material, incased ornot in a non-conductor of heat. --b b fare male 'screws' or couplings@c' is a female screw-coupling attached to and Working freely around onlyone'end, a', of the hose or flexible connection D, so that the otherend, 1c', may have a free llateral motion .in a stufin g-box, f so as tofacilitatethe coupling o1" uncoupling of the cars, andallowfor the freelateral motion of the cars. Both ends of the fixed conducting-pipes d dare' provided witli male screws b' b and stuing-boxes f f', with apacking of rubber, 'g'I g', or other suitable material, making anair-tight connection sof that ythe flexible' connection can becoupled'to either end of the fixed conducting-pipes d d, so that it Willnot be necessary to reverse the ends of the cars to make connection.'

Letter .a' is an extension of the connection into thel stating-box,uponv which thel connec- -tion is 'coupled,takin`g the strain'oii' ofthe screw-coupling, and supporting the flexible connection 'pipe D whenthe cars are unon the ground.

Letter h 'is a flat' steel spiral, iirlnly 'connected with the ends aand e', keeping'the ihose extended and in a proper shape, covered Witha' layer of Holland duck, a layerof vulcanized rubber, theWholerprotccted by a covering of stout leather, forming a dexible hoseor /connectiom which takes the strain caused by the vibratory motion ofthe cars o 'from the ixed conducting-pipes d d, and allows for thefreeturning of curves.
